Pressure Relief Valve DBW30B2N5X/350XYUS6EG24N9K4R12 - Bosch Rexroth R901180785

The DBW30B2N5X/350XYUS6EG24N9K4R12 limits pressure to a value between 2 and 350 bar and provides pilot ports X and Y, so pilot control and spring chamber drain can be routed separately. Flow capacity reaches 650 l/min.

Benefits

• Separately routed pilot ports X and Y, so the set pressure can be commanded by an external valve while the spring chamber drains cleanly to tank.
• Adjustment range 2 ... 350 bar, up to the maximum operating pressure of the valve.
• Seat valve design with low leakage in the closed state.
• Flow capacity of 650 l/min in size 32 at a weight of 6.96 kg.
• Subplate mounting with 2 ports to ISO 6264-10-17.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) to EN 175301-803.

Application

The version with separate pilot ports is chosen where the set pressure is switched or stepped from the process. The spring chamber then drains through its own line to tank, which keeps back pressure from the common return away from the valve. Typical applications are presses and test rigs with several pressure stages.
